ithe ignition system is designed with. special reference to the type of engine under consideration; Each Working" cylinder is equipped with e sparking plug 3% which preferably of the jnnip spark type, and ch plug of the "set ire-l cylind rs is provided 05 eat is adapted To all whom it may concern:

Be it known t}; l. ROY G. Merino; 2t citisen oil? the United S" residing at San in the county Diego and State of California, re s new and usechaflsm, of which the tolvitli e collector or in n once n every revel on to es s either in to sparking devices I creel combustion e11- hcs or its pol object to erm ognition system for own and described in 36, or suiiiciently close thereto to form an suxiliery spark gap for the ignition. system The stationary contact 36, which is in the nature of an elongated plate curved in en arc, is of sufiicient length to be in conducting relation with the brushes for any adjustment of the spark timer between the maximum advanced end maximumretarded position of the letter. The stationary contact 36 is suitably supported on the yoke or supporting frame of the engine, and. insulated therefrom by the block 3 of insuleting material. One Wire of the high tension side of the ignition-system is connected with the contact member 36, as indicated at 38, and the other is suitably grounded on the engine structure. Cooperating with the mechanism for electrically connecting the sparking plugs in circuit is the timer more clearly shown in Fig. 2. This comprises a controller 39 formed of 2 disk of insulating msiterial having so, plurality of equally spaced metallic blocks 40 set in the-periphery thereof. In a two cylinder engine, obviously tivo controller blocks will he employed or moon September 12,1908, tinder Serinl'llo. 334,327 end of which the present cppliceticn is e division. r 23-. further object of the invention is to provide an ignition system which may be readily cpplied to vsrioustyges of rotating explosion engines, and which will permit the ready adjustment oi the spark :tor the purpose of increasing or decreasing the'specd of the engine. Y

With theseend other objects in View, as Will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinorter rnlly (lescrioeo illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the from the spirit or scorn i any of the adventeges of the inve in other Words, there are as many controller in the sccompenyn -s :-l*1gure blocks as there are cylinders.

The arm 42 is pivoted on a lever l -l that is supported on cont-ectwith the metallic member or contact v wire of the low tension, or primary, side of' the ignition system is grounded on the lever 44 so that the. primary current passes from the battery or other source and induction c.oil, through the wire 46, the lever 44;, arm L2, roller 423, controller 89, and the engine back to the battery. Current is thus induced in the secondary circuit and as the current is broken the spark is produced. The second-,

ary current passes through the engine structu'reand spark coil and, then through the brush 35, contact36, Wire 38 to the induction coil. The timer levertt is-insulated from the .machine, a-ndserves to advance or retard the spark merely by adjusting it in. one direction or the other; With a' current distributer-of the characterv shown in Fig. 2, separate circuit connections for each spark plug are dispensed with, thus materially re-' nition system. i

duclng the cost and complication of the ig- I claim v v 1. An nternal combust1on engine having a plurality of rotatable cylinders, a spark plug on each cylinder, a'brush carried directly by each'spark plug, an elongated stationary-contact with Which each brush engages for a time period 'sufiicient to include the limits of advance and retardation of the spark, means for charging each spark plug While its brush is in engagement with the stationary elongated contact, and means for causing the advance or retardation of the spark at will. I

An internal combustion'engine having a plurality of rotatable cylinders, a spark plug on each cylinder, a brush carried directly by each spark plug and extending therefrom in a direction substantially radial spark plug while its brush is in engagement with the stationary elongated contact, and means for causing the'advance or rcta rdation of the sparkat will.

In testimony that I claim-the foregoing as my own, I have hereto affixed my s gnature in the presence of two witnesses.
